I M P ORTA N CE OF P R OP ER FI T FIT THE HEADBAND Proper fit is important both for comfort and optimal noise cancellation performance. 1. Using the left T and right U icons on the headband to orient the headset properly, rotate the side pads into position. 2. Place the headset on your head. 3. Adjust the headband so the side pads rest above your ears.
I mportance of P roper F it CHOOSE THE CORRECT STAYHEAR+ TIPS For optimal audio performance, it is important to choose the correct size StayHear+ tip. Select the size that gives you the best comfort and fit in each ear. To determine the best fit, you may need to try all three sizes. You may need a different size for each ear. NOTE: Without a properly fitting tip, the noise reduction and audio performance of the headset will be degraded.
I mportance of P roper F it Single earbud use When you want to use the headset with one earbud, you can stow the other earbud using the earbud storage hook on the back of the side pad. Earbud storage hook CHANGE THE STAYHEAR+ TIPS 1. H olding the earbud, gently grasp the attached StayHear+ tip and peel it away from the earbud. CAUTION: To prevent tearing, grasp the StayHear+ tip by its base. Do NOT pull on the tip wing. R 2.
IM mportance P ORTA N CE OF of P R roper OP ER FI F it T ADJUST THE MICROPHONE NOTE: By default, the reversible microphone ships from the factory attached to the left side of the headset. If you want to move the microphone to the other side of the headset, see “Microphone Placement” on page 25. 1. Grasp the microphone base, and adjust the boom so the microphone is level with your mouth. CAUTION: Microphone placement is important for clear communication. It can rotate 300°.
IM mportance P ORTA N CE OF of P R roper OP ER FI F it T CONDITIONS RELATED TO FIT In very loud conditions, such as during takeoff, you may experience a brief reduction in noise cancellation as the headset compensates for a momentary pressure change. If this continues when the sound level returns to normal, see “Acoustic Noise Cancellation” on page 20. If it persists, see “Troubleshooting” on page 47.
HEA DSET CON TR OL S POWER ON Press the Power button I. Power button The Power light glows amber then blinks according to the power level. See “Power light” on page 32.
